Chapter 90 covers optical, photographic, cinematographic, measuring, checking, medical or surgical instruments and apparatus, precision instruments and apparatus, etc. Goods of this chapter generally have the characteristics of high technology content and high added value, and are used for purposes such as measurement, detection, analysis, control, or medical diagnosis. Heading 9022 specifically relates to X-ray or radioactive apparatus and related equipment, which are key equipment in the fields of medical diagnosis or industrial inspection. Heading 9022 includes apparatus based on the use of X-rays or of alpha, beta, gamma or other ionising radiation, whether or not for medical, surgical, dental or veterinary uses, including radiography or radiotherapy apparatus, X-ray tubes, high tension generators, control panels and desks, screens, examination or treatment tables, chairs and the like. This heading covers both medical and industrial X-ray equipment, but vehicle-mounted X-ray diagnostic equipment, as a mobile medical unit, is still classified under this heading. Code 902213 is a six-digit subheading: the first two digits 90 represent Chapter 90 (optical, medical, etc. instruments); digits 3-4, 22, represent heading 9022 (X-ray and radioactive apparatus); digits 5-6, 13, represent subheading 9022.13, namely "Other X-ray apparatus for dental use." However, note that 902213 specifically refers to dental X-ray equipment, and vehicle-mounted X-ray diagnostic equipment, if used for dental diagnosis, is classified under this code; if it is for general medical diagnosis, it may be classified under 9022.12 (for medical, surgical, dental or veterinary uses). The code 902213 provided by the user corresponds to "vehicle-mounted X-ray diagnostic equipment," and it is necessary to confirm whether it is exclusively for dental use. According to HS classification, 9022.13 is expressly "for dental use," so only vehicle-mounted dental X-ray diagnostic equipment is classified under this code. This good is vehicle-mounted X-ray diagnostic equipment. If it is designed for dental diagnosis (such as a panoramic dental X-ray machine), it is classified under 9022.13, because this subheading expressly covers X-ray equipment for dental use. If it is used for general medical diagnosis, it should be classified under 9022.12. The vehicle-mounted form does not change its functional classification; the key lies in the use. Therefore, confirming whether the equipment is for dental-specific or general medical use is the key to classification under this code.

Product Name: The specific name of the declared good, which should accurately reflect the equipment's use and type, such as "vehicle-mounted dental X-ray diagnostic equipment." Use: Clearly state the equipment's use, such as "dental diagnosis," "oral examination," etc., to determine the subheading. Brand: Fill in the equipment brand, such as "Sirona," "Planmeca," etc.; if there is no brand, fill in "none." Model: Fill in the specific model, such as "Orthophos XG 3D." Working Principle: Briefly describe the X-ray generation and imaging principle, such as "the X-ray tube generates rays, which are imaged through a sensor." Vehicle-mounted or Not: Indicate whether it is installed on a vehicle, such as "Yes, installed on a medical vehicle." Main Components: List the main components, such as X-ray tube, high tension generator, control console, image receptor, etc. Power: Fill in the equipment power, such as "10kW," to assist in assessment. Customs declaration example: Product Name: Vehicle-mounted dental X-ray diagnostic equipment Use: Dental diagnosis, for oral panoramic and CT scanning Brand: Planmeca Model: ProMax 3D Working Principle: The X-ray tube generates X-rays, which penetrate teeth and jawbone and are received by a sensor and converted into digital images Vehicle-mounted or Not: Yes, installed on a medical vehicle Main Components: X-ray tube, high tension generator, control panel, image receptor, rotating arm Power: 12kW HS Code: 90221300 Mistakenly classifying general medical X-ray equipment under 902213, when it should actually be classified under 902212. Failure to indicate the vehicle-mounted characteristic may lead to omission of regulatory conditions. Inaccurate description of use, such as writing "medical diagnosis" for dental-specific use, causing classification disputes.

The core basis for classification is the equipment's use and function. According to HS notes, subheading 9022.13 is expressly "X-ray equipment for dental use." Therefore, vehicle-mounted X-ray diagnostic equipment, if exclusively for dental use (such as a panoramic oral machine or dental CT), is classified under 902213; if used for general medical diagnosis (such as chest X-ray), it is classified under 902212. The vehicle-mounted form does not affect classification; the key lies in the equipment's designed use. At the same time, it is necessary to consider whether it has other functions (such as radiotherapy), but diagnostic equipment is generally not classified under 9022.14 (other medical use). 902212 Other X-ray apparatus for medical, surgical or veterinary use: 902212 covers general medical diagnostic X-ray equipment, such as chest X-ray machines, orthopedic X-ray machines, etc., while 902213 is exclusively for dental use. If the vehicle-mounted equipment is used for dental purposes, it is classified under 902213; if used for other medical purposes, it is classified under 902212. 902214 Other X-ray apparatus for medical, surgical or veterinary use (non-diagnostic): 902214 is used for non-diagnostic purposes such as radiotherapy, while 902213 is for diagnostic purposes. If vehicle-mounted X-ray diagnostic equipment is used for treatment, it is classified under 902214. 902219 X-ray apparatus for other uses: 902219 covers X-ray equipment for non-medical uses such as industrial and security inspection, while 902213 is exclusively for dental medical diagnosis. If the vehicle-mounted equipment is used for industrial inspection, it is classified under 902219. 902290 Parts and accessories of X-ray equipment: 902290 is for parts, while 902213 is for complete equipment. If the vehicle-mounted equipment is a complete system, it is classified under 902213; if it is only parts, it is classified under 902290. Is the equipment exclusively for dental diagnosis? Is it installed on a vehicle? Does it have X-ray imaging capability? Does it include a complete system rather than parts? Is the description of use clearly dental?

Is vehicle-mounted X-ray diagnostic equipment always classified under 902213? Not necessarily. 902213 applies only to X-ray equipment exclusively for dental use. If the vehicle-mounted equipment is used for general medical diagnosis, it should be classified under 902212; if used for industrial inspection, it is classified under 902219. Therefore, it must be determined according to actual use. How can it be determined whether X-ray equipment is "for dental use"? X-ray equipment for dental use is usually designed for oral examination, such as panoramic machines, dental CT, periapical film machines, etc., with specific exposure parameters and imaging software. If the equipment can be used for all parts of the body, it is not dental-specific. Does the vehicle-mounted form affect the HS code? Usually not. HS classification is based on the equipment's function and use; the vehicle-mounted form is only the installation method. However, note that some countries may have special regulatory requirements for vehicle-mounted equipment, which should be indicated at declaration. What is the main difference between 902213 and 902212? 902213 specifically refers to X-ray equipment for dental use, while 902212 refers to other X-ray apparatus for medical, surgical or veterinary use. The difference lies in use: dental-specific goes under 902213, general medical goes under 902212. How should the "Use" element be filled in at declaration? It should accurately state "dental diagnosis" or "oral examination," avoiding general expressions such as "medical diagnosis." At the same time, specific applications may be added, such as "for oral panoramic and CT scanning." What additional documents are required for vehicle-mounted X-ray equipment? In addition to regular customs declaration documents, vehicle modification certificates, medical device registration certificates for the equipment (if applicable), radiation safety licenses, etc., may be required. The specifics depend on the importing country's regulations. If the equipment has both dental and general medical functions, how is it classified? According to the General Rules for the Interpretation of the Harmonized System, it should be classified according to its principal use. If the principal use is dental, it is classified under 902213; if general medical is primary, it is classified under 902212. It is recommended to provide technical materials to prove the principal use. How can the tariff rate for 902213 be checked? Tariff rates vary by country and trade agreement and may change. It is recommended to obtain the latest rates through customs official websites, tariff query systems, or by consulting a customs broker. At the same time, preferential rates under free trade agreements may be considered.
